Drawdown
How far your portfolio falls from its high — and how much steeper the climb back is.
Why it matters
The math of losses is asymmetric, and nobody warns you until you're inside it.
In plain language
Drawdown is the distance from your portfolio's peak to its lowest point after. From $100,000 to $70,000 is a 30% drawdown — a measure of how much pain the journey included, whatever the final destination.
The cruel part is the arithmetic of recovery: percentages don't cancel out. Down 30% needs +43% to get back. Down 50% needs +100%. The deeper the fall, the disproportionately harder the climb.
This is why professionals obsess over limiting the downside. Protecting the floor isn't cowardice — it's respecting the math.
In real life
Losing half your suitcase weight is quick. Re-earning, re-shopping, and re-packing it takes considerably longer than the airline took to lose it.
In the market
A portfolio that fell 50% in a crash must double just to break even. A portfolio that only fell 20% needs +25% — a completely different recovery decade.
The common mistake
Thinking a 50% loss and a 50% gain cancel out. From 100 to 50 is −50%; from 50 back up 50% only reaches 75.
“The fall is measured in percent. The climb back is measured in patience.”
Quick self-check
Your portfolio drops 25%. What gain does it now need to return to its old high?

+33%. (From 75 back to 100.) Always steeper than the fall — which is the entire argument for not falling too far.
Education, not financial advice. Markets involve risk; nothing here is a recommendation to buy or sell anything.
